Abstract (en)
[origin: EP0251118A2] 1. A process for the preparation of an N-substituted formamide of the formula see diagramm : EP0251118,P4,F1 where R is a radial of a C1 -C8 -alcohol, by reacting formamide with acetaldehyde in the presence of a basic catalyst to give N-(alpha-hydroxyethyl)-formamide and then etherifying the N-(alpha-hydroxyethyl)-formamide with a C1 -C8 -alcohol in the presence of an acidic catalyst, wherein the reaction of formamide with acetaldehyde is carried out in the presence of a C1 -C8 -alcohol, the weight ration of formamide to alcohol being from 1:1 to 15:1.
